摘要 PROBLEM TO BE SOLVED: To easily confirm a range-finding point setting state or a focusing state at low cost by providing a range-finding point display part corresponding to each range-finding point and a focusing display state displaying the result of range-finding in a display device within a finder. SOLUTION: At what range-finding point, among three range-finding points, focusing is performed is displayed on the range-finding point display part 35 of the display device within the finder provided out of the visual field of the finder. The display part 35 is constituted of a left range-finding point mark 35a corresponding to a left range-finding point, a central range-finding point mark 35b corresponding to a central range-finding point, a right range-finding point mark 35c corresponding to a right range-finding point, and a finder visual field frame mark 35d corresponding to the visual field of the finder. Such display is performed by lighting the range-finding point marks 35a to 35c. A focusing mark 37 is displayed in a lit state at the time of focusing, and in a flickering state at the time of non-focusing.
